This is content to describe the display. It can contain HTML such as bold text and links.
This example has two widgets that use the same data.frame but are not connected. What if we used a SharedData object, .e.g.,
df = SharedData$new(mpg)
Note also that this HTML is all on one line and the regular HTML paragraphs are not rendered as expected. So there are additional layout/rendering layers we would have to control/override.
